how to make lzo compression optional?

mgrant

I have some openvpn clients that are using lzo compression. I have this in my server.conf:

comp-lzo

This works fine for clients with 'comp-lzo yes' in their client.conf.

However, I have some Mikrotik routers which do not support lzo compression. Is there some way to make my server support both the existing clients which have comp-lzo in their configs and the Mikrotiks which do not?

Is this what 'comp-lzo adaptive' does? The docs on this are not so clear.

Unfortunately, I have a few hundred vpn clients out there all with comp-lzo enabled; there's no way I modify every client.conf file. Hence, why I'm trying to understand if I can set the server in some mode where it uses it only if the client proposes it.

You can manage per client compression with --client-config-dir

Client config file (as per --client-config-dir above):

      comp-lzo no
push "comp-lzo no"

I realise, you may have looked into my suggestion already ..

I am not aware of any other openvpn directive to achieve your needs than per client.

However, you could setup another server on a different port and direct the clients that do not support compression to use that port and then disable compression on the server ..

Or, you could disable compression completely ..

At this time it is not possible .. but that does not mean it should never be possible .. perhaps a wishlist item 😉
